Divrey Hayamim Alef 23:22-24

Orthodox Jewish Bible

²² And Eleazar died, and had no banim, only banot, and their brethren the Bnei Kish took them as wives.

²³ The Bnei Mushi; Machli, and Eder, and Yeremot, three.

²⁴ These were the Bnei Levi after the bais avoteihem; even the rashei avot, as they were counted by number of shmot by their head count, that did the work for the avodas Beis Hashem, from the age of twenty shanah and upward.
